Kombucha tea is a fermented drink. Even though Kombucha tea is said to have health benefits, it has not been proven by scientific evidence, and there have been cases of adverse side effects reported.
I know of a teenager who has been in remission of ulcerative colitis for months by following Dr. Poley's treatment plan. She decided to try some Kombucha tea due to its advertised health benefits. The brand she tried came from a reputable health foods store and contained very little sugar. Unfortunately she soon had intestinal bleeding, so she stopped drinking the tea and the bleeding gradually disappeared.
You may find that teas such as blueberry, peach, etc. can be a refreshing drink as ice tea in the hot summer. You can drink them without any sweetener or add a little honey.

May you enjoy this last month of summer!
